IMPROVEMENT IN LQCOMOTIVES'.

o I Specification forming part of Letters Patent No. 129,701, dated July 23, 1872.

To all whom it may concern:

e Be it known that I, HARRY WHITAKER, of the city of New YorkVState of New York, have invented Improvements in and Mode of Applying Superheating Steam-Boilers to Locomotives; and I do hereby declare the following to be an exact description thereof,

reference being had to the accompanying draw'ing and to the letters of reference mark` ed thereon making a part of this speciflcation,`

in Which- Figure 1 represents the mode of applying my improved superh eating steam-boiler77 to a locomotive, exhibiting a side elevation, and

showing the superheatin'g-boiler placed between the Vdriving-wheels, connecting the steam-pipe (now in use) on the horizontal boiler with the steam-dome of my vertical boiler, for the purpose of heating the feed- The rebox of the old boiler is out o to make room for my vertical or upright boiler, which is about ten feet six inches in height, and less in height than the dome of the old boiler. The tubes are taken out of the old horizontal boiler that is to be used as a Water-tender. Fig.. 2 represents a vertical section of the boiler, and Fig. 3 a cross-section of the same.

My invention consists in the combination i of my improved superheating steam-boiler77 to locomotives; the boiler being placed in a vertical position between the driving-wheels, and the ordinary locomotive horizontal steamboiler to be used as a water-tender, the shell and all parts of the locomotive (forward of my upright boiler) to be the same now inuse, leaving out the tubes from the boiler, by which I gain great advantages: it saves fuel;

saves the cost and hauling of a tender; is

safer, stronger, and requires less repairs than other locomotives; and adds traction to the rails.

A represents the upright boiler; B B, the driving-wheels of the locomotive; C C, the front wheels; D, the steam connecting-pipe; E, the piston; F, the engineers house; G, the shell of the common horizontal boiler that I use as a water-tender, with the tire and water tubes left out; H, the smoke-box; I, the ashpit; J, the grate 5 K, the nre-box; L, the water-jacket; M, the combustion-chamber; N, the fire-tubes; P, the water-tubes; B, the crown-plate--that is, a circular dome, into which the water-tubes P extend. S is the water-line. Tis the steam-space. U is the tube-sheet, and V the smoke-pipe.

A This boiler can be used `successfully ou city railroads, because it consumes its smoke and sparks, and coal is Ato be used instead of wood. It superheats its own steam, and ef-,

- to secure by Letters Patent, is-

The superheating steam-boiler A, placed in a vertical position between the driving-wheels B B, in combination with the ordinary locomotive steamfboiler Gr, to be used as a watertender, when constructed and operating as herein described, and for the purposes set forth.
